SAWING APPARATUS dPatented July 7, 1931 UNITED 'STATES PATENT oFFicE ALMON E. COMBS AND GEORGE D. FISK, OF FORT DODGE, KANSAS SAWING APPARATUS i Application filed December 6, 1928. Serial No. 324,256.

This invention relates to sawing apparatus, one of the objects being to provide a structure having means combined therewith whereby stock to be cut can be fed automatically to the saw, the feeding means being constantly under the control of the operator.

With the foregoing and other objects in view which will appear' asthe description proceeds the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed it'being understood that changes in the precise embodiment of the invention hereinv disclosed may be made within the v scopeof what is claimed without departing from the spirit of the invention.

fn the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a front elevation of the apparatus.

Figure 2 is a section on line 2 2, Figure 1.

Figure 3 is a top plan view of a portion of the apparatus.

Referring to the figures by characters of reference, 1 and 2 designate standards connected by a lower shelf 3 and a top 4, the standard 2 being extended above the top beyond one end thereof and provided with upper and lower brackets 5 and 6 providing bearings for shafts 7 and 8 respectively. A pulley 9 is mounted on the shaft 7 and another pulley 10 is mounted on the shaft 8, these two pulleys constituting supports for a band saw 11 adapted to work within slot 12 formed in the edge of the top 4.

VAs indicated at 13 one corner portion of the top 4 is cut away so that material falling through this out away corner will be free to drop on to a delivery chute 14 supported beneath the top.

Parallel guide strips 15 are secured on the top 4 and are engaged by a slide 16 one edge 45 of which projects beyond one edge of the top 4 and has depending brackets 17. These brackets are connected by pitmen 18 to wrist pins 19 on pulleys 20 or to similar structures. A shaft 21 that supports the pulleys or disks a0 2O has a pulley 22 secured thereto engaged by a twisted belt 23that receives motion from a pulley 24 loosely mounted on a shaft 25 that is journaled on the shelf 3. A pulley 26 is secured to the shaft 25 and receives motion through a belt 27 from a pulley 28 on the 5% shaft 8 and another pulley 29 on said shaft 8 receives motion through a belt 30 from a pulley 31 on the shaft 32 of an electric motor 33.

A pulley 34 is secured to the motor shaft 32 and is adaptedto transmit motion through a twisted belt `35 to a pulley 36 secured to the shaft 37 of a circular saw 38, this saw being extended upwardly through ar slot 39 in the top 4.

A clutch member 4() is feathered or otherx wise connected to theshaft 25 so as to rotate therewith but slide thereon and this clutch member is adapted to move into and out of engagement with another clutch member 41 carried by the pulley 24. Afoot lever 42 "I5 fulcrumed, as at 43, is extended beyond one side of the structure where it provides a treadle 44 adapted to be depressed by the operator. Then thus actuated the lever 42 will shift the clutch member 40 into engagei5 nient with the clutch member 41, thereby coupling pulley 24 to the shaft 25. When the treadle is released ak spring 45 interposed between the two clutch members 40 and 4l will push them apart and raise the treadle. Sia

Mounted on the slide 16 is a gage strip 46 adjustable angularly about a bolt 47 and having another bolt 43 adapted to slide in an arcuate slot 49 formed in the slide 16. By

ieans of a nut 50 this bolt can be tightened "il in the slot so as to hold the gage strip 46 in any position to which it might be adjusted. An extension lea-f '51 can be hingedly connected to one end of the top 4 and used for supporting wood stock of considerable -S length.

In `practice the circular saw 38 can be employed for cutting stock fed thereto either transversely or longitudinally. lVhen it is desired to cut off lengths of stock and to feed the stock automatically to the band saw, the gage 46 is adjusted to properly feed the stock against the said saw and, by being set at any desired angle, can be adapted to stock of different shapes. After stock has been placed '190 against the gage and back'of the savv 11 the Vtreadle 114 is depressed. This Will couple pulley 24 to the rotating shaft 25 so that the disks or pulleys 20 will be rotated to cause the pitinen 18 to move the slide 16 forwardly and thence backvvardly. Thismovement Will be suiiioient to feed the stock against the saw and to move. 4the table baekward'ly following the severance of the stock, but the movement baekvvardly Will notvv be` suifioient to bring the sto'ek against'the saW 38.' In order; y

to sever the stock lby means of saw 38 it is necessary to place it on the slide close to said saw before the slide begins its vbaolvvard movement. The piece out off by the band saw Will fall off of the end of the slide 16 on to the guide trough 111. j Treadle 44 is of Course released immediatelyvfollowing the feeding operationv so thatthe' parts can'be thus uncoup'led'from the Vpovver mechanism. l

It isy to be understood of 'ooursethat the' Y 11 is to be provided With a guide 52 ofany preferred construction;
